GRB 250114B: Swift-XRT afterglow detection

Swift-XRT has conducted further observations of the field of the INTEGRAL-detected burst GRB 250114B. The observations now extend from T0+11.4 ks to T0+153.7 ks and have a total exposure time of 9.8 ks. . The source previously reported, "Source 2", is believed to be the afterglow. The position of this source is RA, Dec=48.8582, -2.2940 which is equivalent to: RA (J2000): 03:15:25.96 Dec(J2000): -02:17:38.2 with an uncertainty of 7.6 arcsec (radius, 90% confidence). This position is 81 arcsec from the INTEGRAL position and consistent with the reported optical counterpart (Sasada et al. GCN 38950). Comparison of individual observations show the source has faded. The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00021756.
